I have a dandy blower from a unused yard blow up yard toy. a 4 inch sewer hose connector fits right on the outlet and a section of sewer can be run in a small window and sealed up enough to do a bubble test on the roof. I can post a picture if anyone is interested in seeing it.
Many dealers have equipment to do this also for a modest price.
The term sealing is what is commonly referred to as inspecting and re-caulking. It's just another confusing and mis-used term.
When I caulk, I use a small plastic putty knife and gently attempt to level and high spots. It's not necessary except for aesthetics. Clean all the crud you can get off and use a self leveling Dicor caulk liberally. It will flow into and around cracks. Inspect all seams thoroughly and look for holes or tears in the fabric.
Eternabond tape is a very good product and easy for a do it yourselfer. There are many videos and information available.
Do this regularly and your camper will last a long time without any moisture problems.
